Comments about 3/4" Spirovent Jr. Air Eliminator (Sweat):

Installed this in my baseboard system that previously had no bleeders or air removal provision (except for purge valve) when I added a second zone in my basement. After just three days, all "gurgling" after refill was gone and now all my baseboards are providing even, silent heat.
Definitely worth it.

Comments about 1-1/4" Spirovent Jr. Air Eliminator (Sweat):

Use this on the supply side of the boiler before the zones. If the head ever leaks you can buy a replacement head for it,you do not have to replace the entire part. Great because you hear the removal of air instantly.

    Does unit come with a plug in the expansion tank port, or will I need to get one to close that hole?

      The plug is not included. You would need to purchase one separately if you do not plan on connecting the air eliminator to an expansion tank.

  • 1" Spirovent Jr. Air Eliminator (Sweat)

    Q:

    I'm trying to decide between threaded and sweat for the 1" Spirovent Jr. Air Eliminator (VJS100). Are there any rubber seals or anything inside of the unit that I may damage with my average pipe sweating skills? I taught myself plumbing about 6 years ago and can still overdue it when it comes to sweating pipes. However, I've never had a sweated connection leak, can't say the same for threaded. Thank you

      Yes, there is an o-ring. I had the sweat fitting and I unthreaded the top
      and took the ring out while I soldered it. I would suggest, if it works out,
      using the threaded to avoid having to do that.

      I just sweated the 1" copper lines directly to the Air Eliminator. Had
      no problems or issues. Just make sure everything is clean and you use
      the correct flux with lead free solder.

      There is nothing that I’m aware of that can be damaged as long as you concentrate the heat in the area of the actual joints. You can always lay a damp rag on the body of the vent to keep that section cooler during the sweating process (although this will lengthen the time it takes to convert the solder to a liquid by a little). I’ve used the sweat version of this device countless, with no problems. Hope this helps, Scott

      Hi,
      There are nothing to burn at the bottom of the spirovent. If you decide to get the threaded version just put about 7 turn of tape over the thread. There are also 1/2 inch threaded hole at the bottom where you can put an expansion tank or a valve.

      But I suspect those are high up in the vent - far enough away from where
      you'd be making connections. I'm no plumber either, but had no problem
      installing a pair of them. No leaks, and working great.

      Mike, we had the same concerns and had no problem with the valve and our
      sketchy skills. You can unthread the top off the body if you are worried
      but the valve is large enough that the top stays cool while you are sweating
      the fittings on.

  • 1" Spirovent Jr. Air Eliminator (Sweat)

    Q:

    Do I need to try to install this at the highest point in the heating system? Or can I install it on a short horizontal run before the water enters the boiler (this point is a few feet lower than the circuit). It would be between the water supply and the circulator pump.
    Asked on 6/28/2013 by Mike from Albany, NY

    • CUSTOMER CARE

      A:

      Spirovent-style air eliminators do not need to be installed at the highest point in the heating system, but they should be placed on the supply side before the circulator pump. Air eliminators function most effectively when system fluid is as hot as possible and at its lowest velocity.

      Answered on 6/28/2013 by PexSupply Staff from NY
    • VERIFIED BUYER

      A:

      The purpose of this device is to extract air from your system. To
      insure that you do this for the whole system, it should be installed at
      the highest point in the system. Based on your individual system, you
      may get away with installing it somewhere else. If you do that, you
      need to insure that the higher parts of the system are not subject to
      the collection of air bubbles or that the flow thru the higher parts of
      the system are positive displacement. The other alternative is to
      install a manual relief valve at the high point to remove air, but that
      is what this product is for. If this is being installed for someone
      else, put the Spirovent at the highest point. If it is in your home
      system, you need to calculate your tolerance for criticism when a bubble
      causes your pump to cavitate and lose flow vs the effort to do it right.

      Hi Mike,
      Yes, the spirovent needs to stand upright on a horizontal run of pipe on your hydronic system. I also have mine between my circulator pump and my boiler. The nice thing about this unit is it "scrubs" travelling bubbles out of your loop. You will likely still need to air bleed your individual radiators, but this unit helps reduce air from travelling in the lines.
      If you get lots of air in your system, then you likely have a leak which you should also be addressing.
      Good luck!

      A:

      I'm no expert, but my understanding is that the only requirements are that
      they be placed somewhere in the flow, and installed relatively vertically.
      These bleeders operate by capturing air from within the water as it flows
      through. If the bleeder is installed in the feed line, it only gets one
      shot at scrubbing the air out. When fresh water comes in, much of the air
      it carries is dissolved - the bleeder won't catch it. Instead, the bleeder
      should be installed in the zone so it can operate on the water as it flows
      by. It just needs to be close to vertical so the mechanism can function
      properly - air it has scrubbed out accumulates at the top, and when there's
      enough of it the float opens the valve to let the air out.
      I'd expect that any air in the system that's contributing to noise will
      follow the flow around and eventually pass through the bleeder, wherever
      that bleeder happens to be installed. If there is a pocket of air trapped
      in a high-point in the system, and it's out of the way enough to actually
      stay put, then it probably isn't causing any noise (or other problems)
      anyway. Install these bleeders somewhere in the zone - anywhere in the zone
      is fine.
      I have 2 of these in my system: one is in the 1st-floor zone; the other in
      the 2nd-floor zone. Both bleeders are installed in the basement, in a
      6-foot horizontal run, only a few feet above the boiler. Almost the entire
      zone is above its bleeder. These worked great for me. My system had obvious
      sloshing noises and some banging. In just one day these bleeders had the
      system running much quieter. The only noise now is the pinging from the
      baseboards as the metal heats up.
      Hope that helps.

      Well, it depends on how reliable you want your heating system to be. For
      maximum efficiency and reliability, you need to pipe that air vent up
      above your boiler on the primary loop.
      Check you boiler piping instructions for good piping diagrams.

      A:

      I followed what this book told me as I was getting a lot of air in my system:  http://www.amazon.com/Hydronic-Radiant-Heating-Practical-Nonengineer/dp/B0006R478S.  Basically haven't bled a radiator since following his advice, except once in the fall and I basically don't get any air anyway.   
      You want the Spirovent on the suction side of the pump.  You should have a bladder tank screwed into the bottom of the spirovent.  My water supply enters off a tee between the bladder tank and the vent, but I don't think it matters much where the water enters as you really shouldn't be adding water or you have a leak.  The boiler should be on the suction side of the pump as well (before the Spirovent of course)
      Having this setup limits the pressure drop created by the pump. A pressure drop in a system is what leads to air leaving the water.  Also, the Spirovent is located where the pressure is lowest; this is where the air is going to bubble out of the water.  
      Don't think the high point really matters as the spirovent has a screen that  captures microscopic bubbles in the water.  It might remove bulk air too, but it's primary function is to scrub the water of air bubbles.

      I have a couple of smaller air eliminators in my radiant heat systems
      and both work well without any extra hardware. The one in my
      solar/radiant heating system for my workshop is at the top of the
      system, and the one for the radiant heating system in my house is within
      a foot of the high point. Both air eliminators are in the system full
      time (no isolation valve) and I have not had any problem with fluid
      leaking or air in the system after the system is filled and run for a
      few hours to get the last bubbles out.

      I have installed many of these Spirovent eliminators, and I use them in place of the traditional air-scoop and automatic hi-vent. They are wonderful at keeping your systems air-free and quiet. I still install the fast feed/purge valve for the initial pressurization, and for quick re-pressurization during future maintenance. Hope this is helpful, Corhouse Construction, LLC.

      Yes, this micro bubble resorber will create bubbles and eject them from the
      system. It is intended to be placed where the water is hottest and the
      pressure is lowest (suction side of main circulator). If large pockets of
      air are left in the system it may stop circulating water altogether.
